I use AnyDVD and DVD Shrink as well as DVD X copy to back-up my DVDs, but I am stumped in one area - audio. Several DVDs that I have made backups of have veriables in the audio. usually it's at a normal level, but there are times that the sound seems to fade out slightly then come back. It's a gradual decrease and increase but it's enough to make me turn up the volume only to turn it down again after a few seconds. Anyone else run in to this issue? Thanks!
